I was doing some boat/ocean diving last week and on the predive info from the DM we were told the snorkles werent necessary since we will be descending and ascending right next to the boat.
Since I always use my snorkel for the surface interval I left it in place. Well out of 10 dives that week only 3 of them we didnt have a nice little swim to and from the boat.
Moral of the story is you cant predict mother nature and currents. Id rather always be prepared then to be caught with out it.
